Today DEVONthink To Go 2.7.1 has become available on the iOS App Store.
The maintenance release comes with an updated PDF library which fixes a crash during indexing PDF documents. Version 2.7.1 also deletes temporary files used for synchronizing with iCloud as soon as a file is fully uploaded. Direct connections prefer IPv6 now if both IPv4 and IPv6 are available. Finally, the update improves the overall robustness of the app.
You always can find the complete list of all changes inside the app (tap the question mark button on the first screen). We recommend this free update to all users. Update your copy through the App Store app or receive the update automatically, depending on your App Store settings.
